I tested the same jammer device indoors and outdoors at the same time, and found that the shielding radius outdoors is farther than indoor. What is the reason?

Locally, different environmental impacts are also different. The fault area in the open area is larger than that in buildings. Therefore, the measured interference radius is usually better than the actual range. Because the test is in an open area. Because the signal may be blocked / interfered by the stone wall, the grid will form a Faraday cage (including "wrong" lead windows) and metals such as tin foil insulators, reducing the reliability of the wifi jammer indoors. In other words, if you use a jammer indoors, the glass may block the signal due to the wall. You may not be able to interfere with the signal in another room.
